Documents recently obtained by ABC News show that less than two months prior to his disappearance, Aguiar's wife, Jamie, filed to overturn the couple's prenuptial agreement, referring to their relationship as a "living nightmare".

Given that the prenup prohibits Jamie from receiving more than $500,000 of the fortune, it adds intrigue to speculation that Guma may have faked his own disappearance, perhaps to avoid a more costly divorce.

"Ellen Aguiar over here has been on the gravy train for years," said Jamie Aguiar's attorney, William Scherer, who according to WSVN questioned whether Aguiar and his mother schemed to stage his disappearance.

"We have not heard from and have not had any confirmed sightings of Guma Aguilar at this point," testified Fort Lauderdale Police Sgt. Steve Novak in an earlier court appearance.

He'd recently transferred guardianship of the estate in his will from his wife to his mother -- just two months after filing a similar document with the women's roles reversed. But Ellen Aguiar moved to control the fortune before Coast Guard divers had even called off a 2-day search for her son's body, prompting criticism -- and, in court, questions about whether her son purposefully disappeared, possibly with her help.
